Hi All,

I want to build myself a MK 2Viper Jet with a 78" (2 mtr) wingspan or similar size Futura jet, but despite endless hours of searching the Internet and speaking to numerous plan suppliers, I can't find a set of plans or even basic drawings that show the relevant dimensions to enableme to build one.

Thanks in advance for any information you can provide.

Regards

Keith

My suggestion is to import pictures like this one into a 3d cad and work out the plans.

Google Sketchup is for free and easy to use, also with plenty of free tutorials.

I have tried to use Sketch up to determine dimensions from photo,s but this method doesnt appear to be accurate. I can play around and scale photo's but I would need to have photo's from every angle of the plane and some dimensions to start with so thats a non runner. The Viper has been around for a while now so why havn't any drawings been produced?

Any other suggestions of how I can obtain the information to build from.

Buy yourself one of the small ducted fan versions and scale it up. You can sell it after your through with it.

Hi Eric, that Idea did cross my mind but I am not sure how to do it. I read somewhere to fill the internal of the model with expanding foam and then cut the model into slices to upscale but there must be an easier way to determine the dimensions of theViperthan to ruin a perfectly good model.
